19-3214; Rev 0; 2/08 KIT ATION EVALU E L B A IL AVA 1mm x 1mm Video Filter Amplifier with Automatic Shutdown and 2V/V Gain Packaged in a 1mm x 1mm UCSP™ with 4 bumps, the MAX9515 is an ultra-small standard-definition video filter amplifier with automatic shutdown. The automatic shutdown circuitry eliminates the need for a shutdown control. This feature provides intelligent power management by disabling the filter and output amplifier in the absence of a video input signal and/or an output video load. At shutdown, the device only consumes 5µA. The MAX9515 features an internal reconstruction filter that smoothes the steps and reduces the spikes on the video signal from the video digital-to-analog converter (DAC). The reconstruction filter typically has ±1dB passband flatness to 9MHz and typically 50dB of attenuation at 27MHz. The video input to the MAX9515 can be directly connected to the DAC output. The MAX9515 has an internal fixed gain of 2V/V and expects a nominal full-scale video input signal of 1VP-P. The MAX9515 is specified to operate over the -40°C to +125°C automotive temperature range.

Automatic shutdown circuitry provides intelligent power management by disabling the filter and output amplifier in the absence of an input video signal and/or output load. An internal reconstruction filter smoothes the steps and reduces the spikes on the video signal from the video digital-to-analog converter. The reconstruction filter typically has ±1dB passband flatness to 9MHz and typically 50dB of attenuation at 27MHz. The MAX9515 has an internal fixed gain of 2V/V and expects a nominal full-scale video input signal of 1VP-P. +3.3V 5μA VDD MAX9515 AUTOMATIC SHUTDOWN CONTROL LOGIC NO VIDEO SIGNAL VIDEO ENCODER CURRENT DAC IN AV = 2V/V LPF OUT 75Ω BUFFER GND Figure 1. Automatic Shutdown 6 _______________________________________________________________________________________ 1mm x 1mm Video Filter Amplifier with Automatic Shutdown and 2V/V Gain connecting an internal 15kΩ pullup resistor to the output for 1ms. If the output is pulled up, no load is present. If the output stays low, a load is connected. If the input video signal is present and a load is connected to the output, the filter and amplifier turn on and remain on until the output load is disconnected. Automatic shutdown intelligently reduces the supply current based on the input signal presence and output loading (Figure 3). When the amplifier is on, it continually checks if the load has been disconnected by detecting if the amplifier output is sourcing current during a horizontal line time. If no sourcing current is detected within one horizontal line time (approximately 64µs), the load has been disconnected and the amplifier returns to activedetect mode. If, at any time, the input video signal is removed, the MAX9515 returns to standby mode. +3.3V 9μA VDD 0 TO 50mV 1VP-P VIDEO MAX9515 AUTOMATIC SHUTDOWN CONTROL LOGIC VIDEO SIGNAL PRESENT VIDEO ENCODER CURRENT DAC IN AV = 2V/V LPF OUT 75Ω NO LOAD BUFFER GND Figure 2. Active-Detect Mode _______________________________________________________________________________________ 7 MAX9515 Automatic Shutdown The MAX9515 automatic shutdown circuitry reduces power consumption when there is no active video input signal or an output load. In shutdown, the supply current is reduced to 5µA. The video amplifier only turns on when both an active video input signal and an output load are present. The MAX9515 slices the IN signal at 4.7% of the power supply (155mV for a 3.3V supply). If the transitions occur at a rate of 7.3kHz or higher, a video signal is present. When the MAX9515 detects a video signal with sync at the input, the control logic enters the active-detect mode and enables the load sense circuitry (Figure 2). The supply current increases from 5µA to 9µA typically. If an output load is not connected to the amplifier, the MAX9515 remains in active-detect mode. Eight times per second, the load-sense circuit checks for a load by MAX9515 1mm x 1mm Video Filter Amplifier with Automatic Shutdown and 2V/V Gain +3.3V 2.9mA QUIESCENT SUPPLY CURRENT PLUS OUTPUT LOAD CURRENT VDD 0 TO 50mV 1VP-P VIDEO MAX9515 AUTOMATIC SHUTDOWN CONTROL LOGIC VIDEO SIGNAL PRESENT VIDEO ENCODER CURRENT DAC IN AV = 2V/V LPF OUT 75Ω BUFFER 75Ω GND Figure 3. Full-Operation Mode Input Output The MAX9515 video input should be directly connected to the output of the video current DAC. DC-coupling ensures that the input signal is ground referenced such that the sync tip of the composite video signal is within 50mV of ground. Any standard-definition video signal can be applied to the input as long as the signal is between ground and 1.05V when VDD = 2.7V. The MAX9515 output expects to drive a DC-coupled load to ground. The amplifier output stage needs about 300mV of headroom from either supply rail. The device has an internal level shift circuit that positions the sync tip at approximately 300mV at the output. Video Reconstruction Filter The filter passband (±1dB) is typically 9MHz, which makes the device suitable for standard-definition video signals from all sources (e.g., broadcast and DVD). Broadcast video signals are channel limited: NTSC signals have 4.2MHz bandwidth, and PAL signals have 5MHz of bandwidth. Video signals from a DVD player, however, are not channel limited; so the bandwidth of DVD video signals approaches the Nyquist limit of 6.75MHz. (Recommendation ITU-R BT.601-5 specifies 13.5MHz as the sampling rate for standard-definition video). Therefore, the maximum bandwidth of the signal is 6.75MHz. To ease the filtering requirements, most modern video systems over sample by two times, clocking the video current DAC at 27MHz. Applications Information Power-Supply Bypassing and Ground The MAX9515 operates from a single-supply voltage down to 2.7V, allowing for low-power operation. Bypass VDD to GND with a 0.1µF capacitor. Place all external components as close as possible to the device.
